FLASK FOR CASTING HORSESHOES.

SPECIFICATION forming part of Letters Patent No, 389,559, datedSeptember 18, 1888.

(No model.)-

T0 at whom it may concern:

Be it known that l, FRANCIS I. FREEMAN,.a resident of Warren, in thecounty of Trumbull and State of Ohio, a citizen of the United States,have invented certain new and Improved Flasks for Casting Horse and MuleShoes; and I do hereby declare the following to be a full, clear, andcomplete description thereof.

My invention relates to metallic flasks or molds for casting steel shoesforhorses and mules; and the improvement consists in the peculiarconstruction and manner in which the several parts comprising said moldsare arranged in relation to each other.

The object of this improvement is to so construct the molds or flasks asto render them readily separable before the cast-steel shoe begins tocontract while cooling off, thus in no way or place retarding thecontraction of the said shoe, any obstruction during the process ofcontraction necessarily causing breakage in the article cast andrendering itunserviceable.

- That this invention may be fully understood,

reference will be had to the annexed specification and the accompanyingdrawings.

Figure 1 represents a horseshoe cast in and formed by the flask abovereferred to. Figs. 2 and 3 illustrate the face views of each half of themold. Fig. 4 is an inner face view of the center core for said mold.Fig. 5 is a horizontal section of both the sides of said mold and thecenter core ready to be inserted therein in line'a: 00, Fig. 2. Fig. 6is a central vertical section of the mold complete. Fig. 7 is a centralhorizontal section of the same. Fig. 8 is a side view of said mold whenunited and ready to receive the molten material, (steel or iron.) Fig. 9is a front face view of the same. I

Like letters of reference denote like parts in the drawings andspecification.

The horseshoe, Fig. 1, represents the finish ed article when taken fromthe mold above referred to, which mold is formed in sections or parts,preferably of cast-iron. The inner side and the lower side of said shoeare formed by the central core, A, Fig. 4, and the outer side of theshoe is formed within the plate B, Figs. 3 and 5, whereas the projectingheels and toe on the lower side of the shoe are formed by the plate 0,Fig. 2. The plate B contains the body part of theshoe, and also the clipD, as

seen in Figs. 3 and 6 and in dotted lines in Fig. 5. The depression Econstitutes the form of the horseshoe, and diminishes in depth to wardthe central part, F, of the plate B. Into the opening G of the plate 0is fitted the core A,which core is provided with a pin, I, projectingout laterally therefrom. The pin, when inserted into the central hole,J, of the plate B, will retain the plate 0, as well as the core A, inproper relation with the plate B.

The plate 0 is secured to the plate B by means of the hooks K K. (Shownin Figs. 8 and 9.) The hooks arepivoted to the plate B, and engage overpins K, projecting out from the plate 0. (Seen in Fig. 8.) The centercore, A, is held within the plate 0 by means of the lugs L and the barM. Other equivalent means may be employed to secure the different partstogether within the scope of my invention. Only such devices, however,can be used for this purpose which allow ofa ready separation of thedifferent parts of said mold, so as not to restrain the contraction ofthe cast shoe within the same, which is done by removing the core A,preventing the shoe from cracking by shrinkage or cooling.

The shoe-body mainly is formed by the plate B and the center core, A,whereas the heels N N and the toe O are developed in the cavities N Nand O, which are formed by the plate 0 and said core A. The clip of theshoe is cast in the cavity D of the plate B. (Seen in Figs. 3 and 6 andin dotted lines in Fig. 5.)

In Fig. 5 the plates B and G are shown ready to be secured to eachother, having the core A ready to be inserted into thetapering opening Gof the plate 0, after which the core is secured thereto by means of thebar M. The grooves Q Q and nail-cavities S S are produced by the rims QQ and projection S S on the inner face of the core A, Figs. 4 and 5.

Tapering semicircular grooves T U are made on the inner side of saidplates, extending from the cavities O and D to the edge of the plate.These grooves, when the plates are brought in contact with each other,form the gate T and air-holes U U, respectively. The gate T is for thepurpose of conveying the molten steel or iron into the mold when in anupright position, as shown in Fig. 6, while the hole U U enables the airto escape as the steel is filling up said mold. As soon as the moltenmetal in the mold changes from a liquid into a solid state it is ofvital importance that the cast shoe should have unrestricted room tocontract while cooling off. One blow from a hammer will drive the bar Mfrom out the lugs L, and another blow against the projecting end of thepin I will separate the core A from the cast shoe, allowing it tocontract in every direction before being taken from out the mold. Afterthe core is removed from the mold the shoe is still retained therein ateither side of the toe O and at the faces of the heels N N by means ofthe plate 0, as seen in Figs. 5 and 6. To remove the shoe from the mold,the plates B and C must be separated, which is done by unlocking thehooks K K. The shoes are preferably made of steel, which not only givesdurability to the article, but also makes a superior class of castings.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. A flask for casting steel shoes for horses and mules, consisting ofthe plates B C and the central core, A, the plate B countersunk to shapethe outside, top, and clip of a shoe, the

plate 0 perforated to receive the tapering core A and recessed to formheels and toe of a shoe, and the central core, A, provided with curvedrims having projections therein to produce the grooves and nail-cavitieson the bottom of the shoe, and a recess to shape the inside of the shoe,substantially as and for the purpose set forth.

2. In a flask for casting horse or mule shoes, the combination of theplate 0, core A, and plate 13, the plate 0 provided with lugs L at theback side thereof, to receive the bar M and retain by said bar the coreA within said plate 0, the pin I of said core projecting through anopening in the plate B, and pivoted hooks secured to the side of saidplate for engagement over pins projecting out from the plate 0, allsubstantially as described, for purpose set forth.

In testimony whcreofl ailix my signature in presence of two witnesses.

FRANCIS I. FREEMAN.
